• the development of techniques to achieve dimensionality reduction without losing the available information in the data, and
• the search for techniques to represent more dimensions at the same time.
• How does a user's performance compare to a visual-only solution?
• How does a user's performance compare to a noninteractive solution?
• How rapidly is the solution (for example, pattern detection in data) achieved?
Thomas Hermann is a research assistant in the Neuroinformatics Group of the Faculty of Technology, Bielefeld University. His research interests focus on interactive multimodal human–computer interfaces and techniques for sonification and multimodal data exploration. Hermann has a Diplom in physics and a PhD in computer science from Bielefeld University. He is a member of the International Conference on Auditory Display Board of Directors and is a delegate of the European Cooperation in the field of Scientific and Technical Research (COST 287) action on the control of gestural audio systems (ConGAS).
Andy Hunt is a member of the Media Engineering Research Group in the Department of Electronics at the University of York. His research interests include human–computer interaction, interactive sonification systems, multimodal mapping techniques, and new computer-based musical instruments (especially for people with disabilities). Hunt has a BSc in electronics and a PhD in music technology from the University of York. He is chair of the working group on interactive multimedia systems as part of the European Cooperation in the field of Scientific and Technical Research (COST 287) action on the control of gestural audio systems (ConGAS).
